>> +-----------
>> +* IPv4 traffic
>> +* ESP tunnel mode
>> +* EAS-CBC and HMAC-SHA1
>> +* Each SA must be handle by a unique lcore (1 RX queue per port)

>> +Compiling the Application

>> +#. Build the application:
>> +
>> + .. code-block:: console
>> +
>> + make
>> +
>> +Running the Application
>> +-----------------------
>> +
>> +The application has a number of command line options:

>> +.. code-block:: console
>> +
>> + ./build/ipsec-secgw [EAL options] -- -p PORTMASK -P -u PORTMASK --config
>> + (port,queue,lcore)[,(port,queue,lcore] --EP0|--EP1 --cdev AESNI|QAT
>> +
>> +where,
>> +
>> +* -p PORTMASK: Hexadecimal bitmask of ports to configure
>> +
>> +* -P: optional, sets all ports to promiscuous mode so that packets are
>> + accepted regardless of the packet's Ethernet MAC destination address.
>> + Without this option, only packets with the Ethernet MAC destination address
>> + set to the Ethernet address of the port are accepted (default is enabled).
>> +
>> +* -u PORTMASK: hexadecimal bitmask of unprotected ports
>> +
>> +* --config (port,queue,lcore)[,(port,queue,lcore)]: determines which queues
>> + from which ports are mapped to which cores
>> +
>> +* --cdev AESNI/QAT: choose whether to use QAT HW crypto or EASNI SW crypto
>> +
>> +* --EP0: configure the app as Endpoint 0.
>> +
>> +* --EP1: configure the app as Endpoint 1.
>> +
>> +Either --EP0 or --EP1 must be specified.
>> +
>> +The mapping of lcores to port/queues is similar to other l3fwd applications.
>> +
>> +For example, given the following command line:
>> +.. code-block:: console
>> +
>> + ./build/ipsec-secgw -l 20,21 -n 4 --socket-mem 0,2048 -- -p 0xf -P -u 0x3
>> + --config="(0,0,20),(1,0,20),(2,0,21),(3,0,21)" --cdev AESNI --EP0
>> +
>> +where each options means:
>> +
>> +* The -l option enables cores 20 and 21
>> +
>> +* The -n option sets memory 4 channels
>> +
>> +* The --socket-mem to use 2GB on socket 1
>> +
>> +* The -p option enables ports (detected) 0, 1, 2 and 3
>> +
>> +* The -P option enables promiscous mode
>> +
>> +* The -u option sets ports 1 and 2 as unprotected, leaving 2 and 3 as protected
>> +
>> +* The --config option enables one queue per port with the following mapping:

Hi Jerin,
Are you suggesting to have an option so we basically encrypt all traffic
using
a single SA bypassing the SP/ACL ?
Currently the ACL entry contains the SA index in the SA table, so there
is no SA
lookup on outbound.
That might have to change a bit if we were to add IKE support.
